ZE-I-Viking1-p136a.jpgColor snap-shots from Viking 1 (6)121 visite"...Taken early in the Viking 1 Mission, was nicknamed "The American Flag Picture". During the final months of preparation before the landing NASA managers took exception to our decision to feature only the Mars Surface in the first few color pictures. In particular, they emphasized the popular appeal of a color picture looking back across the spacecraft, the American Flag in the foreground and the Martian Horizon in the distance. We temporized; they insisted. Frame (6) composite was the result. The photograph is both pictorially attractive and scientifically useful. The bright ridge in the distance, part of the crater rim catches the morning Sun. Difficulties in precisely balancing the colors are indicated by the violet hue of the blue color chip on the test chart. The relative differences in reflectance that yield a color image are illustrated by the 3 constituent images taken in blue light, green light and red light...".

QB-VikingOne-PIA08616-01.jpgViking One: the Landing Site, 30 years after the landing... (2)88 visiteCaption NASA originale:"The suite of pictures shown here describes the best MOC view of the Landing Site. These were previously released in May 2005, but the MOC team felt that 20 July 2006 is an appropriate time to review this story.
The 1st figure (1) visually tells how the Lander was found. The initial observations of the location of Viking 1, as originally determined by members of the Viking science team based on sightlines to various crater rims seen in the Lander images (black lines), did not show the detailed features we knew from the Lander pictures (2) to be in the area.
Using geodetic measurements, the late Merton Davies of the RAND Corporation, a MGS-MOC Co-Investigator, suggested that we should image areas to the East and North of where Viking 1 was thought to be. Timothy J. Parker of the JPL (Pasadena, California), using sightlines to crater rims seen in the Lander images (white lines), deduced a location very close to that suggested by Davies".
